IMPROVEMENT LN HEDGE-TRIMMERS.

Specification forming part of Letters Patent No. 173,564, dated February 15, 1876 application filed December 18, 1875.

To all whom itmcy concern:

' Be it known that I, EDGAR PORTER SHAW,

of Ohatham Centre, in thecounty of Medina and State of Ohio, have invented a new and useful Improvement in Hedge-Trimmer, of which the following is a specification:

' Figure l is a top view of my improved hedgetrimmer. Fig. 2 is a cross-section of the same, taken through the line a; 00, Fig. 1. Fig. 3 is a cross-section of the same, taken through the struction, light, strong, and durable, and convenient in use.

The invention will first be described in connection withdrawing, and then pointed out-in the claim.

A and Bare two steel plates, of suitable length and thickness, and upon the forward edges of which are formed teeth a b. The teeth a b are made slightly tapering, are about two inches wide at the base, and have spaces about half an inchwide between them. The edges of the teeth a of the upper plate A are made smooth, and the edges of the teeth I) of "the lower plate .B are scalloped. This form of the-edges makes the teeth out better, and prevents the branches or twigs from slip ping out without being cut.

O are the handles, the forward parts of which have shoulders formed upon them to receive the plates A B, and their forward ends are pivoted, the one to a tooth of the plate A,

and the other to a tooth ot' the plate B.

c are short arms, which have lips formed upon the side edges of their bases to overlap the sides of the handles (J, and are secured to the shoulders of said handles by screws 0 The forward part of one of the arms 0 overlaps and is pivoted to the plate B, and the forward part of the other arm overlaps and is pivoted to the plate A. The plates A B are.

. can be trimmed very rapidly and very evenly.

By taking out the screws 0 the plates A B can be readily taken apart for sharpening the teeth a b, or for any other desired purpose.

Having thus described my invention, I-claim as new and desire to secure by Letters Patent The combination of handles 0 O, shouldered on their forward parts, one pivoted to a tooth of plate A, and the otherto a tooth of plate B, with short pivoted overlapping arms 0 having lips upon side edges, the screws 0 and the U-clamps D, to allow the said plates A B to be operated, in the manner and for the purpose specified.
